“No sound using Fios on-demand... Has anyone had any audio problems when trying to watch movies or shows on-demand using Verizon Fios? See what works and what doesn't below. 1. Audio works on the commercials/ads when going on-demand initially. 2. When finding and choosing the show or movie on-demand, the sound stops working. 3. If you turn the TV off and then back on, the sound begins to work as long as you don't turn the Fios box off. It's almost like the TV isn't syncing with the audio when you start the new program. Has anyone experienced this problem? We have not experienced this problem with any of the other TVs in our house when using on-demand. I'm not sure I want to return the TV because everything else is great. Not to mention, the TV weighs 100 lbs. :) Thanks. Curious Dynex Customer”
